The abstract of the patent published by the U.S. Patent and Trademark Office states: "Techniques for managing candidate sets for a user equipment (UE) are described. In an aspect, multiple candidate sets of cells of different classes may be maintained for the UE. Each candidate set may include cells of a particular class. As some examples, the multiple candidate sets may be for cells of different transmit power levels, cells of different association types, cells associated with different resources, etc. The multiple candidate sets may be maintained separately based on applicable criteria and rules. The multiple candidate sets may be used to select a serving cell for the UE and/or for other communication purposes for the UE. In another aspect, one or more candidate sets may be maintained for the UE and may be used for multiple communication purposes for the UE. The multiple communication purposes may include server selection, interference management, measurement reporting, etc." The patent application was filed on July 7, 2009 (12/498,590).

Smead, Lincoln, Calif., John W. Flick, Sacramento, Calif., and Cristene Sellers, Mountain View, Calif., for a "system and method for updating forwarding tables." The abstract of the patent published by the U.S. Patent and Trademark Office states: "A system and method for updating forwarding tables in a blade packet manager is provided. The blade packet manager may include master and slave blades. A master management module on the master blade monitors the slave blades. Network address entry forwarding tables are maintained on the slave blades. A periodic sweep of slave blades for activity information is performed and reports are forwarded to the master blade. The master blade propagates the reported information from the master blade to each of the slave blades to update forwarding tables on each of the slave blades." The patent application was filed on April 30, 2009 (12/433,779). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,416,701&OS=8,416,701&RS=8,416,701 Written by Neha Bharti; edited by Jaya Anand. *** QUALCOMM Assigned Patent for Time Tracking Loops for a Communication System Utilizing a Cyclic Prefix ALEXANDRIA, Va., April 11 -- QUALCOMM, San Diego, has been assigned a patent (8,416,733) developed by four co-inventors for "time tracking loops for a communication system utilizing a cyclic prefix." The co-inventors are Shivratna G. Srinivasan, San Diego, Michael L. McCloud, San Diego, Remi J. Gurski, San Diego, and Sunil Kumar Kandukuri Narayana, San Diego. The abstract of the patent published by the U.S. Patent and Trademark Office states: "Techniques for performing time tracking in a communication system utilizing a cyclic prefix are described. In an aspect, a receiver may detect for large timing errors based on early and late received samples obtained with early and late FFT windows, respectively. The receiver may derive first and second channel impulse response (CIR) estimates based on the early and late received samples, respectively, determine an early channel energy based on the first CIR estimate, determine a late channel energy based on the second CIR estimate, compute an update amount based on the early and late channel energies, and update the FFT window position based on the update amount. In another aspect, the receiver may perform time tracking with an inner time tracking loop (TTL) and an outer TTL. The receiver may update the FFT window position in coarse steps with the outer TTL and in fine steps with the inner TTL." The patent application was filed on June 28, 2010 (12/825,146).

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Embodiments of a method and apparatus for generating an estimated non-linear echo signal are disclosed. One method includes receiving a plurality of data inputs. The plurality of data inputs are partitioned into subsets. A weight vector is computed for each of the subsets. A vector of addresses to memory locations is computed for each of the subsets. Values of interpolants are accessed at the memory locations (interpolation sites) based on the vector of addresses for each of the subsets. The estimated non-linear echo signal based is calculated on the values of the interpolants and the weight vector corresponding to each subset." The patent application was filed on March 20, 2008 (12/077,672).
